ASLAG-FURNACE.

SPECIFICATION forming part of Letters Patent No. 379,411, dated March 13, 1888.

Application tiled September 13, i887. Serial No. 5249.541.

To all vwm, it may concern:

Beit known that I, JESSE E. PEOR, residing` at Chicago, in the county ot' Cook and State of Illinois,and a citizen ofthe United States,have invented a new and useful Improvement ,in Slag-Furnaces,of which the following isa specification,reference being had to the accompanying drawings, in which- Figure lis alongitudinal section ofthe travcling doorgand Fig.2 is a crosslsection through a stove or heat-er, showing the traveling tloor.

This invention relates to means for receiving and delivering the cooled slag from a blastfurnace, which slag has been utilizedV for the purpose of heating or superheating air or generating steam from water in a stove or heater especially designed for that purpose by me, and in which a seriesof circulating pipes and heaters form the stove; and the object of this invention is to dispense with the use of tools and appliances heretofore employed for removing the slag by having the deposit made on a traveling floor, as hereinafter more specitically described, and pointed out in the claims as new.

In the drawings, A represents the traveling floor, formed of a series of iron plates or bars, a, each pivotally connected to a link, a', and the series of links connected one to the other, so as to form an endless carrier, as shown in Fig. l. A

B is a series of rollers lying under the top ofthe door A and traveling with the floor, each roller B being journaled in a link, b, and the series of links being connected one to the other, s0 as to form an endless carrier.

C are rollers located at the ends or turning point of the rollers B, and over which the rollers ride, and by which any liability of the rollers sticking or stopping in turning at the ends of their travel is overcome.

D are sprocket-wheels, two for each end of the tloor A, and mounted on suitable shafts, D', and engaging with the links a', so as to drive the endless tloor. As shown, two sprocketg wheels, D, are provided foreach end; butmore can be used,if desired,and two series of rollers, B, are provided for each side of the door, as shown in Fig. 2.

E is a sprocket-wheel for driving the shaft (No model.)

stove or heater, or otherwise supported.

F is a track, one on each side, and on which the rollers B run, and these tracks, as shown,

are supported on the pipes forming one portion ofthe stove or heater, as in Fig. 2, or in any other suitable manner.

G are side plates, one on each side of the ltraveling door, for protecting the pipe ofthe heater by keeping the hot slag fromroming in direct Contact with the pipe.

- H'is a stove or heater, formed of a series of pipes, c, and headers d, the pipes and headers having a connection one with the other'to permit a continuous flow through them. The rcceiver is located within the central chamber, H, of the stove or heater H, and receives the molten material from the blast-furnace, and this receiver is adapted to be tipped or tilted to allow the molten material to tlow onto the floor A. The receiver is not shown.

The operation is as follows: The molten material from the receiver is allowed to dow onto the floor A and to cool thereon, and the heat from the molten material will act to heat the continuous pipes c and headers cl of the stove or heater H to heat or superheat air passing throughy the pipes and headers, or producing steam from water iiowing through the pipes and headers. The molten material as it cools forms slag. and this slag is to be removed from the furnace, and as this slag lies on the traveling floor A it will be seen that by driving the shaft Dl from the sprocket-wheel E such shaft will rotate the sprocket-wheels D, attached thereto, and these sprocket-wheels, engaging with the links a of the traveling tloor, will advance such floor, the door riding over the rollers B without much, if any, friction, and each plate or bar a of the traveling door, as it turns around the sprocketwheels D at the discharge end, will be tipped by the act of going around, as shown in Fig. l, throwing off any slag which may be thereon and riding around under clear of the slag, so that when again on top it will be ready to receive another charge of slag; and in order to prevent the slag or iron from adhering to the plates as they come around IOO at the receiving end, they pass beneath a hopper, I, charged with sand, by means of which the plates can be successively sprinkled with sand, preventing adhesion of the slag thereto.

It will be seen that the traveling oor,when stationary, receives and supports the molten material deposited thereon from the receiver, and as the slag becomes cool it can be advanced gradually and a new supply be deposited on the portion of the door coming beneath the receiver, and the cooled portion, as it passes out at the delivery end of the stove or heater, will be thrown from the iioor by the tipping or turning et' the plates or bars a, and by this arrangement the slag as it is cooled is carried away and a fresh surface brought into position beneath the receiver for a new charge of slag or molten material, the result being that the molten material is discharged on the traveling floor, cooled, and discharged without the use of tools or other appliances.

The traveling lloor is shown in connection with stoves or heaters formed of continuous ci rcnlating-pip es; but it may be used with other forms of stoves or heaters.

That I claim as new, and desire to secure by Letters Patent` is as follows:

1. The combination, with astove or heater, of a traveling floor composed 'of .a series of and connecting-links b, for giving the iioor af traveling support, substantially as specified.

3. The traveling` floor A, consisting of a se,

ries of plates or bars, a, and connecting-links a', for giving the floor a traveling support, in

combination with the rollers B, connecting-y links b, and anti-friction rollers G, for giving the iioor a traveling support and preventing stoppage of the rollers B, substantially as specified.

4. The traveling tloor A. formed of a series of-plates or bars, a, and connecting-links a',

Yrollers B and conneetinglinks b. and tracks F, in combination with the sprocket wheel D, Shaft D', and sprocket-wheel E, for supporting and moving the traveling floor, substantially as described. p
